andy91145 Posted April 21, 2015 Share Posted April 21, 2015 My car seems to hit a fuel cut on full boost with a plug and play ecu at 10psi when putting it in diagnostic mode there isn't a code it just flashes constantly, any ideas? Quote Link to post Share on other sites
mikey4410 Posted April 21, 2015 Share Posted April 21, 2015 p and p ecus dont have fuel cut as far as I know mate so thats weird. Quote Link to post Share on other sites
gazza g Posted April 21, 2015 Share Posted April 21, 2015 Which ecu is it? Constant flashing means no codes are stored Quote Link to post Share on other sites
russ78 Posted April 21, 2015 Share Posted April 21, 2015 (edited) some less popular P&P ecu's like HRF don't remove fuel cut strangely enough what ecu is it ? are you sure its genuine as a while back a guy was swapping the jam lids onto stock ecu's Edited April 21, 2015 by russ78 Quote Link to post Share on other sites
andy91145 Posted April 21, 2015 Author Share Posted April 21, 2015 It's a H.R.F V300, it did remove fuel cut, it's only started happening since having the cams fitted Quote Link to post Share on other sites
daniel_g Posted April 21, 2015 Share Posted April 21, 2015 Is it just a missfire at high rpm and not fuel cut? Quote Link to post Share on other sites
andy91145 Posted April 21, 2015 Author Share Posted April 21, 2015 Not sure it's just exactly the same experience as boost cut, very violent cut, Big Bang out of exhaust and the engine management light comes on for a bit Quote Link to post Share on other sites
